Guide rail configuration, conveyor and method for conveying containers

A guide rail configuration suitable for guiding containers in a conveyor, the guide rail configuration comprising at least one guiding structure, including:

• a guide element for guiding a container, the guide element comprising a guiding portion, a support and a carrier, wherein end portions of the guiding portion are connected to the support;
• wherein the guide rail configuration further comprises:
• an attachment member providing a mounting portion for mounting the guiding structure to a portion of the conveyor,
• an electric actuator, configured to move the guide element relatively to the attachment member, wherein the guiding portion comprises, in the conveying direction, an inclined portion which is inclined in the conveying direction, a substantially flat portion and a portion declining towards the support, such that the guiding portion is partially distanced from the support,
• and wherein the guide rail configuration further comprises:
• a first shaft and a second shaft connecting the attachment member and a vertical support supporting the guide element, wherein the carrier is mounted to a support body of a vertical support via screws such that, the guide element and the vertical support are movable together, wherein the support body of the vertical support comprises longitudinal through holes for the screws to be inserted through them upon mounting, the guide element is shiftable in a vertical direction by partially releasing the screws so as to position the guide element in a vertical direction, and
• a detector, in particular a distance sensor or a camera, configured to detect a distance to a lateral side of a container conveyed by the conveyor or a lateral dimension of the container, wherein the electric actuator is activated on the basis of a measurement signal from the detector.
